Electric vehicles (EVs) offer a promising solution to mitigate climate change and environmental pollution, with research focusing on improving their efficiency and driving range. Among the key components of EVs are compressors, which are essential for air conditioning (AC) systems and battery thermal management, in EVs an separate electric motor is needed for their operation. This paper explores the design and optimization of a stator-magnet transverse-flux linear oscillatory machine (SMTLOM) for compressor applications in EVs. The SMTLOM features permanent magnets embedded in the stator, offering advantages such as simplified installation, enhanced protection against vibrations, and reduced reliance on rare-earth materials. The machine operates in two modes: a low-current efficiency mode for minimal energy consumption and a high-current power mode for heavy-load operations. A comprehensive 3D finite element analysis was conducted to optimize the SMTLOM’s performance while minimizing the volume of permanent magnets. Results show possible usage of SMTLOM in compressor. The findings highlight the trade-offs between force generation, efficiency, and material usage, providing valuable insights into the potential of SMTLOM technology for EV compressor applications.
